Maximum lot coverage is set by municipal zoning under MGL c.40A. Residential districts commonly cap coverage at 25-40 percent; urban lots allow more.
Lot coverage, defined in most Middlesex County bylaws as the percentage of a lot occupied by buildings and sometimes impervious surfaces, is regulated at the municipal level under MGL c.40A. Suburban single-family districts typically cap coverage at 25 to 40 percent. Urban communities like Cambridge and Somerville use higher caps or Floor Area Ratio (FAR) instead. Some bylaws separately limit impervious surface to manage stormwater under MS4 permit obligations from EPA and MassDEP. Paved driveways, patios, pools, and accessory structures often count toward coverage. Exceeding caps generally requires a special permit or variance from the ZBA.
